Thanks to its latest update, Line now offers “hidden chats,” which are messages that are automatically deleted after a predetermined period. To send and receive hidden chats, just tap the name of the friend you're chatting with at the top of the chatroom, and select the new Hidden Chat option in the drop-down menu. Note, though, that hidden chats not may not be supported yet in your country.

The new Line update also brings improvements to Timeline notifications, design tweaks, and bug fixes.
